“I would say it would be best to describe as a sudden and violent expansion of the air molecules in that vehicle,” Peach told the Sun.

Rob Kemp, from the Baltimore County Fire Department, explained what caused the explosion to CBS.

“The aerosolized deodorant was inside of the car, created a flammable atmosphere, which he was not aware of,” he said, “and then when he lit his cigarette, he created a spark for the explosion to occur.”

The driver of this car used spray deodorant, lit a cigarette and set off an explosion, police say.
